DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection head body having a horizontal nozzle portion communicating with a vertical nozzle portion fitted to a stem projecting from the top of an aerosol container, and an aerosol covering at least both sides thereof. A base end of a pipe support arm that supports a flexible pipe-shaped long nozzle connected to a lateral nozzle portion, the base end of the pipe support arm being provided with a jet head base mounted on the top of the container. The present invention relates to an ejection head with a long nozzle supported by an arm holder protruding forward from an ejection head base so as to be able to rotate downward.

[0002]

2. Description of the Related Art A jet head of this type is disclosed in
It is well-known from Japanese Patent Publication No. 65062, and can be stored by folding downward along a container when not in use by using the flexibility of a long nozzle as a content of an insecticide, a cleaning agent, and the like.

[0003]

However, since the ejection head is of a push button type, the ejection head is apt to be erroneously operated. In particular, in the case of a long nozzle, when the ejection port is separated from the ejection button, the operator tends to notice it late. There is also.

In view of the above, the present invention has been made to provide an ejection head with a long nozzle capable of preventing an erroneous operation by focusing on the existence of a pipe support arm which is turned downward during storage. Aim.

[0005]

According to the present invention, there is provided, in accordance with the present invention, a lateral nozzle communicating with a longitudinal nozzle which fits into a stem protruding from the top of an aerosol container. Having a jet head body having at least two sides, and a jet head base mounted on the top of the aerosol container covering at least both sides thereof, and supporting a flexible pipe-shaped long nozzle connected to the lateral nozzle portion. In a jet head with a long nozzle supported by an arm holder portion projecting forward from the jet head base, the base end of the support arm rotates the pipe support arm from forward to downward. The rear end of the main body is supported by the rear end of the base of the jet head so that the main body of the jet head can swing up and down. A lever is provided, and an arm holder portion is formed by extending an upper surface portion of the ejection head base covering an upper portion of the ejection head body forward so as to reach at least a front end of the operation lever, and at least a front end portion of the arm holder portion is formed. It is characterized in that a base end of a pipe support arm having a length reaching the operation area of the operation lever is supported.

When the long nozzle is stored, the pipe support arm supporting the long nozzle is turned downward and is placed in front of the operation lever.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An ejection head with a long nozzle according to an embodiment of the present invention will be described with reference to FIGS. As is well known, a mounting cap 2 mounted on the top of the aerosol container 1 has a built-in valve mechanism and has a stem 3 in an upwardly biased state protruding therefrom. The ejection head includes an ejection head body 10 fitted to the stem 3 and an ejection head base 20 attached to the mounting cap 2 to cover the ejection head body 10, and the ejection head body 10 is vertically attached to the ejection head base. It is swingably supported.

The ejection head body 10 has a stem 3 at its lower end.
And a coaxial longitudinal nozzle portion 11 along the stem 3, a lateral nozzle portion 12 communicating with the upper end thereof forward, and a front wall at the front end of the lateral nozzle portion. An operation lever 13 is provided to protrude forward from the portion 12a and extend obliquely downward toward the front, and is integrally formed of synthetic resin. Injection head base 20
The cap 23 has a circumferential surface mounted on a circular curl portion of the mounting cap 2, the center of the upper surface is raised, and the side portions 21 on both sides which cover the side surfaces of the ejection head main body 10 and cover the upper side. It has an upper surface portion 22 and is integrally formed of synthetic resin.

The rib surfaces 25 to 27 are provided between the side portions 21 on both sides.
Is bridged. An arm portion 24 extends rearward from an intermediate position of the vertical nozzle portion 11, and a locked claw 24a is formed at a rear end portion thereof. On the other hand, the vertical rib surface 25 at the rear end of the jet head base 20 has an engagement hole 25a.
Are formed. Thereby, the ejection head body 10
Is supported by the ejection head base 20 such that the locked claw 24a is engaged in the engagement hole 25a and can swing up and down.

A long nozzle 37 having a flexible pipe shape is connected to the front end of the horizontal nozzle portion 12. Upper part 2
2 is extended so as to occupy a position forward of the operation lever 13 to form an arm holder portion 31. On both sides thereof, there is provided a side surface portion 31a in which the vertical width of the side surface portion 21 is gradually narrowed, and a bearing hole 32 is formed at a front end portion thereof as shown in FIG. Pins 35 a protruding from both sides of the base end 35 of the pipe support arm 30 that supports the long nozzle 37 are rotatably inserted into this bearing hole.

As a result, the pipe support arm 30 is brought into contact with the upper surface 2 by frictional engagement between the side surface 31a and the base end 35.
2 while being supported at a substantially horizontal forward position along with a downwardly slidable storage position. The long nozzle 37 includes the arm holder 31 and the pipe support arm 30.
, Is inserted into a pipe portion 36 formed at the tip of the pipe support arm 30, and further projects forward. The length of the pipe support arm 30 is set so as to occupy a position below the operation lever 13 during storage. It is preferable that the length of the pipe support arm be set so as to reach the operation area of the operation lever 13, at least, just before the lower end curved portion 13a. On the other hand, the length of the long nozzle 37 is set so as not to exceed the bottom surface of the aerosol container 1 during storage.

The operation of the ejection head constructed as described above is as follows. When not in use, as shown in FIG. 4, the pipe support arm 30 is folded downward to
, And is held in the retracted position by frictional engagement between the base end 35. In this state, the operation lever 13 is covered with the arm holder 31 at the upper side, and the pipe support arm 30
Are placed in front and face, so that it is difficult for the operation lever 13 to be touched by the hand, and erroneous operation is avoided.

In use, when the pipe support arm 30 is rotated to a forward position along the arm holder 31, the long nozzle 37 guided by the pipe support arm projects forward from the pipe support arm 30. Therefore,
The front of the operation lever 13 is opened and becomes operable. When the operation lever is pulled, the ejection head main body 10
The long nozzle 37 housed in the arm holder 31 with the lower part opened is slightly bent so that the operating force is hardly increased, and the lower part is swung downward with the engagement hole 25a as a fulcrum, and the stem 3 is moved downward. Let it.

[0014]

According to the present invention, since the ejection head with the long nozzle is configured as a trigger type in which the pipe support arm faces the front surface of the operation lever during storage, erroneous operation is less likely to occur.
